High Industrial Tariffs & Peak Demand Surcharges

Industrial units in Bihar face commercial electricity tariffs between ₹7.80 and ₹9.50/unit from NBPDCL and SBPDCL, coupled with steep maximum demand charges (MDI). With motor loads and thermal heating running during day shifts, electricity constitutes up to 25% of operational manufacturing costs.

  • Continuous industrial tariff escalations erode manufacturing profit margins against national competitors.
  • Summer daytime cooling and motor start surges cause costly contract demand overshoot penalties.
  • High diesel generator operating costs (₹28–₹34/unit) during daytime grid tripping or maintenance.
Technical Specifications for Industrial Plants & Manufacturing
Daytime Load Alignment:70% – 90% heavy daytime machinery load
Typical Sanctioned Load:50 kVA – 500 kVA (HTS/LTIS)
Required Roof Space:3,000 – 35,000+ sq. ft (Tin shed or RCC)
Power Factor Standard:Maintained at ≥0.95 with APFC panels
Bihar DISCOM Tariff Class:LTIS / HTS Commercial Rate
Statutory Note: Commercial meters receive ₹0 PM Surya Ghar residential subsidy. Solar power economics are driven purely by bill savings and 40% accelerated depreciation tax shields under Section 32 of Income Tax Act.

Section 32 Income Tax Benefit

Accelerated Depreciation: Write Off 40% In Year One

Under the Indian Income Tax Act (Section 32), eligible commercial and industrial solar power plants qualify for 40% accelerated depreciation in the first year. This substantially lowers your taxable corporate profit, creating a direct tax shield that effectively pays for 25–30% of the project capital cost.

*Assumption: Based on ₹8.20/unit blended industrial tariff, 1,450 kWh/kWp annual yield, and 25% corporate tax bracket. Consult your Chartered Accountant for exact corporate tax implications.
25-Year Cumulative Savings₹1.8 Cr – ₹6.5 Cr+

Frequently Asked Questions

Industrial Plants & Manufacturing Solar Questions Answered

Can industrial solar be installed on corrugated tin or PEB sheds?

Yes. We use specialized non-penetrating aluminum clamps (standing seam) or structural EPDM-sealed self-drilling fasteners engineered to withstand 150 km/h wind gusts without causing roof leaks.

Does an industrial solar plant synchronize with our diesel generator (DG)?

Yes. With a zero-export DG synchronization controller, the solar inverter modulates its output automatically so it safely supplements the generator without causing reverse current damage.

What are the net-metering limits for industrial connections in Bihar?

Under BERC regulations, net-metering capacity is permissible up to 100% of your sanctioned contract demand (up to 1 MW depending on transformer capacity).
